To all whom it may concern Be it known that I, Alma-Np MONARD, c tizenof Sw tzerland, and a resident of thef city of New York, borough of Queens, 1n

a the needle-carrying sectl thecounty of Queens and State of New York, have invented a new and Improved F'ber-PhonograplrNeedle Cutter, of which the following is a full, clear, and'exact de-' scription.

This invention for trimming or relates to a cutting device pointing fiber phonograph needles, and it has for its general objects to simplify the construction and cutting devices of this characbe reliable and eflicient in use, to manufacture extremely handy improve and operation of ter so as to comparatively inexpensive to manipulate.

Another object of the prove cutting devices which comprises a pair invention is to im of that -character of hingedly connect-- Referring to the 'drawing, A designates cutting device, and B the blade-carrying section, said sections, bcingsubstantially like the handle members of a pair of scissors so as to fit respectively the midde finger and" thumb of the hand in which the device is held and'operated,,th e elements-A and B having openings 1 and '2, respectively, to receive the finger and thumb. The opposite (in or ;element of the ends of the sections A and B are pivotally connected together by a screw bolt 3 which has a spring washer i and a nut 5, wherebythe said elements can be maintained tightly together. The inner or opposed faces,0f'the sections A and B are flat, and on th e'secti'on .B is fastened a flat blade C, against which ed elements that are adapted to fit the thumb that by a movement of the elements,

and second finger, like the handle members of a pair of scissors, one element having a-; needle-holding device of novel form and arranged in a simple and novel manner so, similar tothe'closing of a pair of scissors, the blade willtrim the tip of a fiber needle.

\Vith suchiobjectsfinview, and others which will appear as the description proceeds, features of construction and arrangement of the invention comprises varlous novel parts. as will be set forth with particularity in the following description and claims appended hereto.

' In the accompanying drawing which illustrates one embodiment of the invention, and

wherein similar characters of reference indicate corresponding parts in all the views, Figure 1 is a perspective view of the cutting device; Fig. 2 is a perspective view of the blade-holding section with the blade in position; Fig. 3 is a plan view of the inner face of the needle-holding section of the device: Fig. his a view of the inner face of the blade-holding section with the blade re moved; Fig. 5 is a sectional view through the device, taken in the plane of the needle. when in position to be trimmed and showing the blade in the act of trimming the tip of the needle; and Fig. 6 is a plan view of the lines in its initial posh lines in its final position.

' cutting edge will have a the inner face of the section A is clamped by the pivot bolt 3. The blade C ing 6 has an openfor holding the blade in place, the other means being a lug 7 on the section B, which lug fits 'into an opening 8 in the opposite end of the blade from" the opening out the bolt 3 the sections A connected and the blade C off the pin 7 f0r the urpose of sharpening the cutting edge 9. This cutting edge 9 is arranged obliquely to the longitudinal axis of the. nieniber B, so that in operation the drawingicut on the cutting edge 9 of and B are dis-.

needle. Spaced from the the blade and integrally formedon the inner.

face of the element B'is a rest or seat 10 which, as shown in Fig. 5, is slightlythan the cutting edge 9 of the blade (I, such seat or surface 10 serving ner end of the needle to form a rest therefor and thereby limit the thickness of the shaving that is cut off the tip of the needle. The element B has a slot cutting edge 9 so that needle can-drop out.

The means for holding the needle on the upperelement A of the needle cutting device comprises a triangular guide opening 12' which passes from the top entirely through the element A to the inner surface thereof, the opening being triangular in form so as to conform to the cross-sectional shape of the. fiber needles to be trimmed. One wall of the passage or needle-holding guide is formedby a spring 13 which has a member extending into the needle-receiving opening 12 to engage one of the flat sides the shaving from the for the .pivot 3 to pass therethrough, I so that the latter serves as one ofthe means 6. By taking can then be lifted lower to receive the in- 11 directly under the I thereof, such spring being fastened by a screwor other means 14 to the element A The spring serves to-act on the needles in such a manner that they will all have the slot 16, the relative same pitch or inclination when they are in The opening and clo's-' position to be cut.

ing movements of the elements A and B are limited by a pin '15 on the element B'engag ing in an arcuate slot 16 in the element A, which slot is concentric-with the pivct reeeiving openings 17 of the said elements, and by the pin 15 engaging the ends of the movement ofthe elements A and B is limited.

In operation the device is held in one hand withthe thumb and middle finger engaging in the openings 2 and l of the ele ments B and A, respectively, and with the.

- other hand the needleto betrimmed is inserted in the needle holder 12 and pushed in far enough to bear on the rest or surface 10 of the element B when the device is open, that is to say, when the grip ends of the elements A and B are spread as far as they will go. The elements A and B are then brought together, and in'so doing the cutter passes from the full to the dotted line position, Fig. 6, andtrims the end of the needle, '.f.:;the trimming action being illustrated in Fig. 5. The needle is then removed to make 'way for the next one to be trimmed.

From the foregoing description taken in I connection with the accompanying drawing, flthe advantages of the construction and gmethodof operation will be readily understood by those skilled in the art to which the invention appertains, and while I have described the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of-the appended claims.

Having thus described my invention, I

:1 claim as new and desire to secure by Letters Patent 4 1. A hand tool for trimming fiber needles,

comprising a pair of hingedlv connected members shaped to be gripped by the thumb by one hand, the same comprising a pair of elements, a pivot eonnectingthe elements,

one of the elements having-an aperture for receiving the needle to be trimmed, ablade fastened to the other. element and lying between both'elements, said blade having an opening through which the pivotipasses and means for limiting the relative movement of the elements to a range preventing the uncovering of the cutting edge'of the blade.

3. A fiber needle'trimming. tool of such size and shape as, to be held in and operated byone hand, the same comprising a' pair of elements, a pivot connecting the elements, one of the elements having an aperture for receiving the needle to be trimmed, a blade fastened to the other element and lying between both elements, said' blade having an opening through which the pivot'passes and means for limiting the relative movement of the elementsto a range preventing the uncovering of the cutting edge of the blade, the blade-carrying element having a surface adjacent the cutting-edge and slightly be-- low the level of the latter for forming a rest with which the endof the needle normally engages, there being-an opening in 'the blade-carrying element between the cutting edge of the blade and the said surface for permitting the needle shavings to pass. 7

In testimony whereof I have signed my name to this specification inthe presence of two subscribing witnesses.
